PEST-containing nuclear protein regulates cell proliferation, migration, and invasion in lung adenocarcinoma

a IHC results of PCNP expression in different clinical stages of human lung adenocarcinoma tissues and adjacent tissues (left: ×400; right: enlarged). b IHC sum scores were adopted to compare PCNP expression in different clinical stages of human lung adenocarcinoma tissues and adjacent tissues. c Representative results of PCNP protein expression in fresh human lung adenocarcinoma tissues (T) and adjacent normal tissues (N) detected by Western blotting. Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) was used as the loading control. d Statistical results showed that the protein levels of PCNP were significantly elevated in fresh human lung adenocarcinoma tissues compared to adjacent normal tissues. Data are presented as mean？±？standard error of the mean (SEM). **P？<？0.01 compared with adjacent normal tissue
